100% polyester, 250gsm Take on anything in the Regatta thor zip neck fleece! This unlined garment still packs a decent 250gsm to keep you toasty while working. The fleece cuffs and adjustable drawcord at the hem work together to keep the chill out and help you get on. A zip neck fleece is a great alternative to sweatshirts but has the added bonus of being able to vent at the chest/neck. Also features two front zip pockets to store belongings and warm your hands.
